Houston at Seattle

Seattle won 1-0 on Saturday as Hisashi Iwakuma threw seven shutout innings and Robinson Cano had an RBI single. Mike Montgomery will get another chance to start after a fine performance last Sunday when he gave up just one run and five hits in 6 1/3 innings while not walking a batter as the Mariners beat Kansas City 8-5. The right-hander's overall numbers this season include a 2.06 ERA allowing 13 earned runs in 56 2/3 innings. Houston is 29th in the Major Leagues with a .231 batting average against left-handers. Collin McHugh is 5-6 with a 4.50 ERA, and he allowed four runs and eight hits in six innings in the Astros' bizarre 10-9 win over Oakland on July 8, but he hasn't won a decision since May 30. In one appearance against the Astros last year, Montgomery gave up one run in six innings. Seattle has won five of its last six home games. Play the Mariners.
